HUNTSVILLE, Ala. (WHNT) – A judge sentenced Marcus Jackson to jail for 50 years. Jackson is accused of sexually abusing a 9-year-old boy. A prosecutor told WHNT NEWS 19 there were six counts against Jackson.

Numbers are an important thing to Jackson right now. He will somehow find the time to count to 18,250, the number of days in his 50-year sentence.

“He looks like everyone else you know. He doesn’t have the big sex offender tattoo. He looks like a clean-cut, dresses well, speaks well and earns the trust of others,” said Madison County Assistant District Attorney Gabrielle Helix.

Jackson pleaded guilty this week to four counts of sodomy and two counts of sexual abuse of a minor under the age of 12.

“It means day for day. He will go away for 50 years,” added Helix.

Huntsville Police arrested Jackson in July 2011.

Helix says Jackson, who worked at two Huntsville City Schools at the time, committed the crimes over a one-year period.

“He sodomized and sexually abused the little boy, in his care , to the point that the little boy thought it was normal behavior,” added Helix.

Helix says the 9-year-old realized something was not right while watching a sex abuse video at school.

A judge determined this week Jackson’s alleged recorded confession would be played during trial. Helix says that development prompted Jackson to plead guilty.
